Sea-Cucumber
a marine animal related not distantly to the sea-anemone, starfish, and sea-urchin. In external appearance the cucumber looks like a fat worm, but the skeleton of the starfish is represented by a tough, muscular body wall, in the skin of which scales, plates, wheels, and anchors of lime are scattered. The sea-cucumber feeds on minute animals and organic particles extracted from the sand. A repulsive species inhabits the coral reefs of Malaysia. The stout, worm-like individuals attain a length of six to twenty-four inches. The bodies are slit and dried for food. Under the commercial name of trepang, large quantities are imported to the markets of the Chinese, by whom a bowl of trepang soup is regarded as a luxury.

Sealing-wax Impressions
Sealing-wax is a very handy and useful substance for obtaining any particular impression to be afterwards inclosed within or attached to a pattern for moulding in sand. The wax must be of good quality and melted in a metal vessel over a lamp, after which the pattern can be pressed down upon the wax just before it congeals, and a beautiful impression will result if the pattern is thoroughly clean. Sealing-wax impressions make good moulds for plaster.

Seating
A guide-bearing or rest for cores or mould sections. In vertical loam-work the cope or the core, and sometimes both, are made as separate portions of the mould, and must be lowered into their respective positions when the mould is closed together in the pit. In order that this may be done accurately, a tapered seating is formed at the bottom of the mould, extending some few inches below the casting. By this device the smallest end of the core is made to enter at the widest diameter of the seating, and is thus guided to the bottom-bearing, when the sides meet close together at a true centre. The cope is the opposite to this, its widest diameter seeking a true location by inclosing the small end of the seating first, and gradually embracing it closer and closer until the bottom-bearing is reached, when the diameters correspond and the section is central. The tapered sides of an ordinary core-print represent the seating for a core. See COPE-RING; PRINT; GUIDE.
